Windows 2003 Server SP1 Blocking Internet Access

Hi!

I installed Windows 2003 Server SP1 onto a machine running a
non-Microsoft mail server. Everything seemed fine, except that the mail
server was inaccessible from the Internet. As we needed a quick
resolution, we removed the service pack.

Yesterday I installed the service pack on a machine runing a
non-Microsoft FTP server and a few IIS web sites. Everything appeared to
work fine from within our network, but again, nothing was accessible
from the Internet.

No other configuration changes had been made and I checked that the
Windows firewall was off. As there is no obvious cause of this I don't
know where to look to resolve it, so I again uninstalled service pack 1
and everything worked fine again.

I really would like to know what the problem is or what configuration
needs to change, so I can keep the machines up to date. I expect it is
something trivial and obvious, but I don't know what it is and I can't
find any other references to the problem.

Any suggestions would be appreciated.

regards,
Alan.

Just guessing - check the web service extensions settings in IIS. Your
applications may be using libraries or script files that are prohibited by
default, and perhaps the SP reset those settings....
